Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

The May 2018 Stereophile helps to roll out Wilson's new, "smaller" Yvette speaker. Though I did not get much from the review I was interested to read that Wilson (finally) intends this "smaller" speaker to be qualitatively like its big speakers, and ...

Dear Romy,What would be your suggestion on the operating point and OPT impendance if I were to drive a single driver Back loaded horn speaker with over 102db/W? Knowing that you have mentioned a range of operating points in the forum, I still not too...

Hi Domidaw, it looks like your amplifier is working pretty much correctly. The plate current in the output tube is a little below the recommended range (180 mA versus 200-280 mA in Romy's diagram) but too low is better than too high and you can adjus...

By virtue of the internet facilitated 'brain merging' technique; the world has now witnessed a speaker born of the joined brain wave efforts of 97,3% of the registered users of DIYaudio.com. Behold! : http://www.danielhertz.com/products/m1http://www....

I was listening last night the HF section of MiniMe. It was interesting and frankly very promising. The RAAL 70-20XR were fine and he JBL5 did splendid. They are not properly integrated, were not measured and were made up to work together well, it wa...

I do not know what happen between amplifier and speaker but I think matching of amplifier and speaker is one of the most important things is audio.
matching is not just about dynamics/driving or having enough power , it is about perfec...

Sure, it is not a big deal to listen a single-driver speaker. However, if we presume that by means of audio means we are able to make any difference in auditable experiences, and if to capitalize on this difference is you objective (of the object...

Recently I was playing with my horns, running with across my room, trying to hit with them my Cat…. When I settled down at the place when I need them to be I one more time faced a problem of cables. Whoever use multi-channel systems and do milliampin...

Alex, contrary to the numerous speculation that many people more or less reasonably spread about the subject, my experience indicates that there are no such a things as “preferable crossover frequencies". The chosen optimum crossover frequencies are...

hello kids, a few weeks ago i started my hunt for a pair of speakers....i've been attached to my big system with a pair of headphones for the past year and feel its time to get some speakers to listen to music with (plus, i think my ears are now...

What speakers are your using? The “4R at about 80 Hz before going back up their average 8 Ohms at 30 Hz” is not good for SETs. I prefer to have 16R and do not let it to drop below 12R. Lamm is quite fixable with loading, probably because ...

So, I am of the opinion that most anyone can hear the differences. We just don't understand the physics of why it makes a difference. Just make sure you do it in a double blinded fashion, and be ready to accept that some...

Thank you for giving this matter your attention. Jorge, I was intending that the AK151 be employed within a horn. Further, once I had settled upon the driver compliment, it was my intention to retain the services of Jeffrey Jackson, since I am not su...

There has been a low-ish buzz in the hi-fi rags for a while now, to the effect that perhaps we should reconsider "neutrality" and return to the musical-instrument-type speakers of yore. Of course any sea change is good for the Hi-Fi Industry, just a...

[quote user="Simon"] I hope to hear your impressions of the extent of the differences between the Macondos with the waterdrops and new stands to how they may have sounded previously. [/quote]
Yes, there are differences between the “tripoded” Macondo...

[quote user="drdna"]Thanks tuga. It is a nice article, but my French is a little rusty. It seems that he does very little more than explain the limitations of stereo versus binaural reproduction.
From this came the schools of thought of quadropho...

Romy consider that the engineers who did your Altecs in their worst nightmare could not imagine their lovely cinema speakers would be used with solid state amplifier which badly distorts on LOW power levels. It has 100 crappy watts and the first watt...

I can understand wanting to reach out to audio people everywhere, but think that this speaker is a joke for many of us here. It certainly has nothing to do with advanced audio or evolved music reproduction. Even on a DIY site, how much traction does ...

I think the most room friendly and the most universal Danley speaker is the SM60. It has a 5 inch coax and two 8 inch bass speaker in a tricky molded horn, and small, light enough to use it with a standard telescopic pro speaker stand and keep it abo...
